I would call cocain and crack the worst of them all for society. All Addicts I knew, who totally lost controll about their consume & life, always called out Cocain as pure evil. So for example, they used other drugs, even heroine, to control the cocaine indused crave for more cocaine. Even before they were addicts And under the influence of cocaine they did a lot of evil stuff, like manic violence against people. With heroine they “just” lay around.

Edit: I have tried either. So its just Media and personal information by others. So i cant tell something valid(?)
